BetterImage

Stop hand-making og:images. Save a design in the betterimage.io editor, then sign a URL per page with @betterimage/cards (zero dependencies, Node, Bun, Deno, edge) or call the REST API. The image renders on first fetch and is cached at the edge, so there is nothing to host and no headless browser to run. Text, size and pictures are per-call fields, so one template renders a whole blog or product catalogue. The editor itself is free with no signup: paste a link or pick one of 100+ designs and export link previews, YouTube thumbnails, Instagram posts, stories and Pinterest pins from one card. $4.99 once removes the watermark. There is also a remote MCP server for Claude, Cursor, VS Code, ChatGPT and Gemini CLI: make a social card from any page URL, check how a link previews on X, Slack and Discord, and generate meta tags from your assistant. API: free tier with 25 watermarked images a month, Starter $9/month for 500 clean images.
